1460602 - Investigate error triggered in devtools application panel mochitests

Status: RESOLVED WONTFIX

(DevTools :: Application Panel, enhancement, P3)

Description

[Julian Descottes [:jdescottes]]

While running the mochitests, often while unregistering workers, we get the following stack trace:

 0:07.74 INFO Console message: [JavaScript Error: "error occurred while processing 'listWorkers: [Exception...

This doesn't seem to affect the tests, but we should still investigate. Maybe the root cause is similar to Bug 1447197, which shows a similar stack trace, but with very different STRs

[:Harald Kirschner :digitarald]

Given the work that went into SWs and the tools, should we leave this bug open?

I think we can close as wontfix, this was only with the old implementation. Thanks for the ping Harald!
